CARPET-CLEANER.

SPECIFICATION forming part of Letters Patent No. 236,831, dated January 18, 1881.

Application filed November 15, 1880. (No model.)

. To all whom it may concern:

Be it knownthat I, WILLIAM M OARTHUR, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Carpet-Cleaning Machines, of which the following is a specification.

My invention relates to certain improvements in tumbling-reels which are used for cleansing various articles and substances, and which consist of cylindrical or many-sided vessels having trunnions adapted to bearings, so that after the articles to be cleansed have been deposited in the vessel the latter may be rotated, the contents being thereby agitated and the cleansing efi'ect produced by abrasion or impact.

My improvements relate to a tumbling-reel especially adapted for cleansing carpets, the objects of my improvements being to insure the thorough overturning and agitation of the carpet in the reel and to provide for the carrying oft of the dust.

In the accompanying drawings, Figure 1, Sheet 1, is atransverse section of my improved tumbling-reel for cleaning carpets, with its inclo'sing casing; Fig.2,a longitudinal section of the same; Fig. 3, Sheet 2, an end view, partly in section, of the reel; and Fig. 4, an enlarged section of one end of said reel.

The reel A is, in thepresent instance, of octagonal form, and is hung within a casing, B, having a suitable outlet or chimney. The

' sides of the reel are made of slats, as usual,

and within the reel are alseries of radial lifters, D, extending from each of the angles of the casing a certain distance toward the center of the reel. 'Eaoh of these lifters D is composed of a number of metal bars extending longitudinally from one end frame, E, of the reel to the opposite end frame. The reel has a central rack, F, also composed of bars extending longitudinally from one end frame to the other. said rack in the present instance consisting of four rows of bars, each row projecting radially from the center of the reel, and being arranged midway between two. of the lifters D.

The carpet being deposited in the reel and the latter rotated, thelifters D will elevate the mass of carpet to a point above the center of the reel, and will then permit said carpet to drop onto the central rack, which, as it rotates, will carry the carpet around and cause the overturning of the same prior to lettingit fall into the'bottom of the reel. By thus catching and overturning the carpet in its fall from the upper to the lower portion of the reel the thorough agitation and exposure of all parts of the carpet are insured, and the seams of the carpet are not so likely to be injured as when the carpet falls from a point above the center of the reel directly to the bottom of the same.

In order to carry off the dust removed from the carpet I rely partly on the draft of the chimney with which the casing B is provided, and partly upon the currents of air thrown into the reel through openings at in the ends of the same, these openings being covered with wire-gauze or perforated plate. The currents of air are induced either by stationary vanes 11, secured to the inner faces of the driving-pulleys d on the end frames of the reel, -or by means of rotary fans 0, the shafts of which are adapted to bearings guided in frames secured to said pulley d, the shaft of each fan carrying a pinion, f, which engages with a cog-wheel, m, secured to a sleeve capable of turning on the trunnion of the reel.

As the reel is turned in one direction the cog-wheel m may be turned in the opposite direction, so as to impart the necessary movement to the fans 0.

Air-ducts n serve to supply air to the fans, and there should be such a joint between the pulleys d and the casing B that the fans can derive their supply of air more readily from these ducts than fromtheinterior of the casing.

The boxes carrying the shafts of the fans are acted upon in both directions by springs s, so that said boxes and the fans and pinions are at liberty to yield radially to accommodate themselves to inequalities in the cog-wheel m, the tension of the springs being regulated by a set-screw.

Although I have shown both stationary vanes and rotating fans as a means of inducing draft, either of these means may be adopted, and in some cases it may be found snfficient to combine them with one end frame only of the reel.

I claim as my invention- 1. The combination of a tumbling-reel with lifters D and a central rack, F, as set forth.

2. The combination of the tumbling-reel having slotted or perforated sides, and having openings in one or both ends, with a casing,

:0 B, having a chimney, as set forth.

3. The tumbling-reel having slotted or perforated sides and gauze-covered openings in one or both ends, as specified.

4. The combination of the reel, having open- 15 ings in one or both ends, with fans carried by the reel, for inducing currents of air to enter the reel through said openings, as described.

5. The combination of the reel adapted to rotate and having openings, as described, the

20 fans, and an inclosing casing having an air duct or ducts, as set forth.

6. The combination of the reel adapted to rotate and. having openings, as described, the fan-shafts carried by the reel and having pinionsf, and the cog-wheel m, adapted to en- 25 gage said pinions, as set forth.

7. The combination of the reel adapted to rotate and having openings, as described, the fan-shafts carried by the reel and having pinions f, and the cog-wheel m, carried byasleeve o capable of turning independently of the reel, as described.

8. The combination of the reel, the cog-wheel m,and fan-shafts having pinions f,and adapted to spring-bearings on the reel, so as to be ca- 5 pable of yielding radially therein, as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
